  • H2S Emissions Control at Geothermal Plants

    The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a turbine to ...
